Abstract (en)
[origin: WO2020107001A1] Polymeric sheets of the invention comprise sequential layers as follows: a topcoat layer, a polyurethane-based carrier layer, and an adhesive layer. The polyurethane-based carrier layer is formed using essentially no chain extender having a molecular weight of 350 grams/mole or less, resulting in a relatively low storage modulus polymeric sheet. Such polymeric sheets are particularly useful for application to surfaces having a concave topography.
